Crest 3D Whitestrips Luminous Levels 9 Whiter Teeth Whitening Kit, 10 Treatments, 20 Count

They work so easily. Just make sure you use your fingernail to push the strip into the crevices between your teeth for a great fit. Your teeth will be so white. I love these. They are better and cheaper than having the dentist do it for you. The strips are a lot less time consuming as well.You can still talk with them on your teeth and go about your day until you take them off. It is only a few minutes.

I’ve used the Crest Whitestripes for years now-except during pregnancy, but people always ask how I’ve managed to get such white teeth. If you use them correctly and for the right amount of time-the effects are long lasting. I’m not a coffee drinker and don’t drink tea a lot-do perhaps that helps make a better impact. I’ll always do this…price is right too!

I noticed a difference even after the first strip.

very pleased

I'm changing this review from a 1 star to a 4 star. Although the box of strips was nearly squashed flat, and the first strip I used was stuck to the wrapper, the strips do seem to be OK.My experience with this particular product arriving smashed has jaded me to order this again. I'll pay a little more and buy it from Walmart.As for the Crest 3D white strips Levels 9, I've used this before with noticeable results. I haven't used the stronger strips because Levels 9 do not cause me to have any sensitivity.

The media could not be loaded. I received this package through USPS. It was in a bubble wrap package but it still looks like it has been run over by a truck. I am happy with the product, but not how I received the package.

Wish these didn’t hurt after using

Highly recommend. If you haven't tried them recently give it a second chance. I did and I'm very satisfied
